A smart Pickering emulsion catalytic system is first constructed, which not only exhibits fivefold reaction rate enhancement effects in comparison to the conventional biphasic reactions but also can be demulsified by tuning pH at the end of reaction, allowing for in situ recycling nanoparticle catalysts.

The test researched the influence of layered coke charging, sandwich clamping coke charging and central coke charging with edge delaminating on the development of carbon solution reaction in shaft and the reduction of the iron-bearing burden on the condition of the same proportion of high and low reaction coke. It showed that the reduction degree of the layered type coke distribution is the best, and the loss of carbon solution is the minimum using the same proportion of high reaction coke and low reaction coke. Compared with the other two type coke distribution, the layered type coke distribution is promising to increase reaction efficiency in blast furnaces and decrease the energy consumption of blast furnace melting.

Pt-Ru@CP-MWNT catalysts were prepared by radiolytic deposition of Pt-Ru nanoparticles on conduction polymer (CP) coated multi walled carbon nanotubes (MWNTs) surfce. Three different types of conducting polymers; polypyrrole(PPy), polyaniline(PANI), and polythiophene (PTh), were coated on the MWNTs surface by in situ polymerization. Then Pt-Ru nanoparticles were deposited onto CP-MWNTs composite by the reduction of metal ions using gamma-irradiation to obtain Pt-Ru@CP-MWNT catalysts. The size, morphology and composition of Pt-Ru@CP-MWNT catalysts were characterized by SEM, TEM and elemental analysis. The catalytic efficiency of Pt-Ru@CP-MWNT catalyst was examined for CO stripping. Pt-Ru@PPy-MWNT and Pt-Ru@PANI-MWNT electrodes show enhanced activity for electrooxidation of CO and methanol over Pt-Ru@PTh-MWNT catalyst.

The aggregates of pentacenequinone, HPB and PDI derivatives 3, 5 and 7 having aldehyde groups bind strongly with Ag+ and serve as reactors and stabilizers for the preparation of AgNPs at room temperature. In situ generated AgNPs show high catalytic efficiency for industrially important organic dye degradation.
